Lower margin of pronotum with an upcurved lamina forming 

 lower border of antennal trough, genal ridge prominent but not pro- 

 duced; margin of vertex and frons elevated and granulate; face 

 distinctly inwardly angulate at junction of frons and clypeus; pro- 

 notum angulate-emarginate posteriorly; veins of tegmen tending to 

 be granulate, veins always distinctly so; claval veins uniting at or 

 beyond middle of commissure; margin of tegmen serrulate apically. 

 All species with carinae of head more or less fuscous-edged. 



Cenchrea fulva VAN DUZEE 

 (1909 Bui. Buf. Soc. Nat. Sci., ix, p. 195) 



This large species recorded only from Florida may be 

 readily distinguished by its pinkish color. It differs from 

 heidemanni Ball by its narrow and deeply sunken vertex 

 and frons and the fulvo-testaceous elytra, which in heide- 

 manni are milky- white; from uhleri at once by the small 

 size of the latter and creamy elytra, margined with fuscous. 



The original description is here quoted. 



"Very closely allied to Heidemanni Ball but with a narrower and 

 more deeply channeled front. Elevated margins of the vertex as 

 high as the width of its carinate base. Front distinguished from 

 the vertex by a slight angle but the dividing line not at all carinate; 

 narrow, but little broader at apex; the edges greatly elevated; middle 

 line feebly carinate. Eyes vertical, sinuated behind and strongly 

 narrowed below. Second joint of the antennae large, ovate, but not 

 nearly attaining the margin of the post-ocular cavity in which it 

 stands; setae short, black. Pronotum shorter than the dorsal aspect 

 of the vertex, angularly emarginate behind; on either side produced 

 in a semicircular auriculate cavity for the reception of the antennae; 

 the elevation of the posterior wall of this cavity is about equal to the 

 length of the pronotum. Mesonotum transverse, convex, polished and 

 very obscurely tricarinate on the disk; the obtuse triangular apex 

 depressed. Elytra long and narrow; the outer claval nervure dis- 

 tinctly granulate. Genital plates of the male with their inner margins 

 strongly toothed at the middle leaving a rounded opening at base 

 and an oblong one apically. Length to tip of the abdomen 3*& mm.; 

 to apex of the closed elytra 6% mm. 



Color obscure rufo-fulvous, deeper on the abdomen and paler or 

 subtestaceous on the elytra; eyes, slender edge of the facial carinae 

 and stiles of the male black. Wings and plates of the male whitish, 

 tfie nervures of the former brownish; apical margin of the elytra 

 slightly enfumed and very minutely serrate.
